Abstract: 

A total of 109 fungal isolates were collected from the wheat fields in various regions of Lorestan province, during 1994-95 and in a complementary survey in 2003-04. All isolates were recovered from samples having crown and root rot symptoms. Of these, 45 isolates belonged to Fusarium and the remaining belonged to other fungus genera. Fusarium verticillioides, F. proliferatum, and F. equiseti had the higher frequencies with 62.2, 4.5, and 4.5% of the isolates, respectively. Fusarium avenaceum, F. semitectum, F. sambucinum, F. chlamydosporum, F. lateritium, F. acuminatum, F. subgulatinans, F. reticulatum, and Fusarium sp., were the least frequents. Among other fungi, isolates of Bipolaris hawaiiensis, and B. sorokiniana comprised 18.4 and 13.8 % and Rhizoctonia solani comprising 1.8 % were the most and the least frequents, respectively. The species F. reticulatum, Fusarium sp., Bipolaris hawiiensis, Alternaria triticina, and Curvularia senegalensis isolated and their pathogenicity was confirmed for the first time from the root and crown of wheat in Iran. Pathogenicity of F. lateritium and F. subglutinans on wheat is also reported for the first time.
